$\begin{array}{l}\text{Here,\hspace{0.17em}}\\ \\ \Rightarrow \sqrt{{\text{(8)}}^{\text{2}}\times \text{7}\times {\text{(5)}}^{\text{2}}-\text{175}}\text{ =?}\\ \\ \Rightarrow \sqrt{64\times \text{7}\times 2\text{5}-\text{175}}=?\\ \\ \Rightarrow \sqrt{11200-\text{175}}=?\\ \\ \Rightarrow \sqrt{11025}=105\end{array}$

Hence, Option A is correct.
